Common Metric Units Mini-Challenge

Match each tool to what it measures and the unit's symbol.

📏 Reading metric tools Every science tool measures a quantity (like length or volume) and shows it in a specific unit, written with a symbol. For each tool below, match what it measures, the unit you would actually read off it, and that unit's symbol.
Drag the correct quantity, unit name, and symbol onto each tool, or click a label to select it and then click a tool zone to place it. You need to fill in all three rows for every tool before you can submit.
